Application filed January 2'7, 1902. Serial No. 91,466. (No model.)

To all whom it may concern:

Be it known that I, ALFRED CHARLES BUNNE, a citizen of the UnitedStates, residing in New York, borough of Manhattan, in

5 the State of New York, have invented certain new and usefulImprovements in Signal-Lanterns, of which the following is a specification.

This invention relates to certain improvements in signal-lanterns forrailway, trolley, and other cars, stations, &c., the object of theinvention being to provide means by which the color of the light can bechanged from white to red or green, so as to overcome I 5 the necessityof a separate lantern for each color and reduce thereby the number oflabterns required for signaling purposes; and the invention, consists inthe combination, in a signal-lantern, of a lamp, casings above and belowsaid lamp, a wire guard-frame connecting said casings, telescopingglobes, one in each casing, and means for placing either the upper orlower telescoping globe in posi tion around the lamp; and the invention0on sists, further, in certain details of construction and combinationsof parts, which will be fully described hereinafter and finally pointedout in the claims.

Inthe accompanying drawings, Figure 1 is 0 aside view of my improvedsignal-lantern, both globes being in this view withdrawn into theircasings, the lanterns in this case emitting ordinary white light. Fig. 2is a vertical central section through the lamp with the globes in thesame position as in Fig.

1. Figs. 3 and 4c are also vertical central sections, respectively, withthe upper globe lowered and with the lower globe raised. Fig. 5 is ahorizontal section on line 5 5, Fig. 3; and

0 Fig. 6 is a bottom view of the lantern.

Similar-letters of reference indicate corresponding parts.

Referring to the drawings, A represents the oil font or lamp proper, andB the chimney,

5 which maybe of any desired shape and which is made of ordinaryuncolored glass and retained in position between a flange a. of thehousing of for the oil-font A and flange a of the perforated chimney-capa The housing ct is attached in any suitable manner to the may bewithdrawn.

lower casing G, which casing comprises a perforated outer wall or shell0 and a bottom 0, closing the casing at or near the lower end. The cap ais attached in any suitable manner to the upper casing D, whichcomprises a perforated wall or shell d, to which is hinged at d a top orcover d closing the casing at its upper end. The cap a is shown attachedto the cover (1 and extending partly within and partly without the sameand pro- .vided at its exterior part with perforations for exit of theproducts of combustion from the lamp. The cover is normally retained inclosed position by asuitable spring-catch, one member (1 of which isattached to the casingwall d and the other member d to the cover (1 Thecasings C and D are rigidly connected by means of vertical guide-rods,ofwhich two, 6 and 6, arranged diametrically opposite each other, areshown, and by means of a guardframe E, of the usual construction,extending at one side of the lantern, unbroken at the outer side of therod e, and at the other side terminating at each side of the rod e, soas not to cover said rod, but leave the same unobstructed, so that aguide-sleeve e can be readily slid by the user of the lantern up- Wardlyor downwardly on said rod e.

For retaining the oil-font A in its housing a a spring a of suitablestrength is secured at one end to the bottom 0', at its lower side, andretained normally in position across the bottom of the oil-font A bymeans of two keepers a and a To remove the font, the spring is releasedfrom the open keeper a by the user and moved into the position indicatedin dotted lines in Fig. 6, when the font The bottom 0' is preferablyprovided with a suitable downwardly and outwardly projecting flange 0the whole being detachably secured to the shell. 0 by a bayonet-joint cand catch 0 or other suitable means.

Upon the guide-rod e is arranged a sleeve 6 to which and to a guide 6 onthe opposite rod e is connected a ring e supporting the lower member 6of a globe F, the upper members e e of which are adapted to telescopeone within the other and all within the member e, and the latter withthe others adapted 1 :0 to enter within the upper casing D, so as to beobscured when not in use. The uppermost member 6 is provided atdiametrically opposite points with guiding projections 6 permittingmovement of the member vertically in the casing and limitingits downwardmovement-and the downward movement of the entire globe by abutment atthe lower end of the slots 6 the members of the globe being connectedeach with and dependent from the next by means of suitable top andbottom flanges, as clearly shown in the drawings. The globe is ofsuchsize as to be moved up and down freely at the outside of the chimney Band is of such length as when completely extended to cover the entireeX- posed portion of the chimney, so that the light given by the lanternis entirely of the color of the globe. The individual members of theglobe may be made of glass, celluloid, or other sufficiently transparentdurable material. To the guide-sleeve e is attached a suit-able hook orlink, which when hooked over a projection 12 on the guide-rod e or othersuitable point of support maintains said sleeve in raised position, andthereby the entire globe in telescoped state within the casing.

The lower globe G is constructed, in a manner similar to the upper one,of telescoping members 12 b b b, of which the lowermost is connected byany suitable means, as pins 1)", projecting from supports 5 with thecasing O, and the upper largest member 19 is guided by means of guides band 6 connected with a supporting-ring b on the rods 6 e, the guide ebeing made in the form of a sleeve and forming the main guide, the lowerglobe being extended or telescoped by the user when the upper globe isin raised position by sliding this sleeve e upward or downward on therod 6. The sleeve is provided with a suitable spring-latch b adaptedwhen the globe is raised to engage a notch b of the rod e and retain theglobe Gin raised position, the lantern in this case giving light of thecolor of said globe.

To the upper casing is pivoted a suitable bail d For facilitating theoperation of raising the upper globe from lowered or extended intotelescoped position a suitable telescoping mechanism is provided, whichis preferably connected with the bail. This mechanism, as shown,consists of a leverf, pivoted at one end to the guard-frame E andconnected at its opposite end by means of a link f with the guide 6 ofthe globe. At an intermediate point is connected by a suitablepin-andslot connection f an operating-rod f which is guided in asuitable sleeve secured to the casing D, said rod extending in upwarddirection and being guided at its upper portion by sleeves f f on thebail d. The rod f is articulated at two points in its length f frespectively, and said guide-sleeve f of the casing, together with theother parts, are so constructed and arranged that when the globe is inraised position one of said ara lamp,

ticulations is adjacent the pivot f of the bail, and when lowered theother articulation is in position adjacent the said pivot, so that ineither case the bail is not of necessity retained alwaysin uprightposition,which would be the case were the rod f not so articulated; butthe bail is thereby permitted to fall into the customary position ateither side of the lantern when notin use. The upper end of the rod f ispreferablyhooked or looped, as atf, for conveniently grasping the same.By this mechanism the upper globe, which will customarily be red incolor, can be operated with the greatest facility and retainedconveniently by the user in raised position for any desired time withouthooking the link b over its projection. When said link is hooked overits projection b, not only is theglobe retained in raised position, butthe operatingrod also is retained with the articulation f in positionfor permitting falling of the bail into downward position when thelantern is set down. Furthermore, the bend of the operating-rod at itsarticulation when the bail is in downward position serves to retain theglobein raised position even though the link be not hooked over itsprojection Z).

The lower member of the globe G need not be formed of transparentmaterial and is preferably of such width as not to project above thecasing-wall c.

The articulations f f are preferably doubly articulate by means of theshort links shown to provide for slight play of the parts.

In the lantern shown the globe descends by gravity when released, theoperating-rod serving for raising the same. By swinging the bail to oneside, releasing the catch d d, and swinging the cover (1 into openposition the chimney can be removed and access had to the interior ofthe globes for cleaning. When the sleeve (2 is in lowermost position,the spring-catch 12 engages a notch I9 of the rod 6, thereby retainingthe lower globe G securelyin telescoped condition within the lowercasing.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. In a signal-lantern, the combination of a casing,and a globe formed of a plurality of individual members or sectionsarranged concentrically within each other, each section connected at oneend with the next inner section and at the other end with the next outersection, and each section of less width than the distance from saidcasing to the flame of said lamp, said sections when extended insuccession extending to and at the sides of said flame, substantially asset forth.

2. In a signal-lantern, the combination of a lamp, casings, one aboveand one below the flame of said lamp, and a globe formed of a pluralityof individual members or sections arranged concentrically within eachother, each section of less width than the space between said casingsand each section connected at one end with the nextinnersection and atthe other end with the next outer section, said sections when extendedin succession closing the space between said casings, substantiall yasset forth.

3. In a signal-lantern, the combination of a lamp, casings, one aboveand one below the flame of said lamp, a globeforined of a plu rality ofindividual members or sections arranged concentrically within eachother, each section of less width than the space between said casings,and each section connected at one end with the next inner section and atthe other end with the next outer section,

said sections when extended in succession closing the space between saidcasings, a bail connected with one of said casings, and an operatingdevice connected with said globe and bail, substantially as set forth.

4. In a signal-lantern, the combination of a lamp, casingsabove andbelow said lamp,

a guard-frame connecting said casings, guiderods within said guard-frameand protected thereby, a telescoping globe in each casing,

means for moving one of said globes into position inclosing said lampand means for moving the other of said globes independently intoposition inclosing said lamp, substantially as set forth.

5. In a signal-lantern, the combination of a lamp, lower and uppercasings, telescoping globes in said casings, guide-rods connecting saidcasings, a guard-frame also connecting the casings, and located outsideof the guiderods, a bail, a lever mechanism connected with the upperglobe, an articulatedoperating-rod connected with said lever mechanismand guided on said bail, and means for looking the upper globe in raisedposition, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.
